Change oil in pump after first 50 hours of operation and
every 250 hours of operation after that. With the pump
warm from operation, remove plug on bottom of pump
and drain oil into suitable container. Replace plug. Fill to
approximately half-way on the sight-glass with SAE 15W-
40 Mineral non-detergent oil using the checking procedure.
Approximately 1000mL of oil are required to change the
pump oil.
At 1000 hours of use (less in severe use conditions) the
Senator G2 should be taken to a Jetwave Independent
Service Center for pump seal and valve service.
Gearbox Lubrication
Check the gearbox oil level prior to each use. Place the unit
on a level surface. Wipe any dirt and debris from the area
of the dipstick and sight-glass (Figure 16). Oil level should
be at the middle of the sight-glass. If needed, remove the
dipstick and add SAE 85W-140 gear lubricant oil, fill to
half-way on the sight-glass. Do not overfill, reinstall dipstick.
Change oil in gearbox every 500 hours of operation. With
the gearbox warm from operation, remove plug on bottom
of gearbox and drain oil into suitable container. Replace
plug. Fill to half-way on the sight-glass with SAE 85W-140
gear lubricant oil. Approximately 300mL of oil are required
to change the gearbox oil.
Preparing Pump for Cold Weather
Storage
If the unit will be stored under conditions where the
temperature is near or below 0°C, the unit must be properly
prepared. If water freezes in the pump, it can damage it.
After the tank is drained (if applicable), remove the hose
from the water inlet filter. Open all valves in the system and
use compressed air to force any water out of the system.
This can also be used to remove water from the hoses.
Machine Storage
Store the unit in a well ventilated area protected from the
weather elements. Keep the machine in a locked area
that is out of reach of children and people unfamiliar with
High Pressure Cleaners. This machine can cause serious
injury in the hands of untrained users. See Maintenance
section for information on cold weather storage. See
engine operator’s manual for specific information on engine
storage.
